The bandwidth is defined as the frequency at which the sensitivity is 0.707 of the sensitivity at DC or the lowest AC frequency (a drop of 3 dB). [13] The oscilloscope's response drops off rapidly as the input frequency rises above that point.
Digital technology allows the information to be displayed with brightness, clarity, and stability. There are, however, limitations as with the performance of any oscilloscope. The highest frequency at which the oscilloscope can operate is determined by the analog bandwidth of the front-end components of the instrument and the sampling rate.
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
The 2465 has a bandwidth of 300 MHz, the 2465A 350 MHz, the 2465B 400 MHz. The 2467 is a special case, having a micro-channel plate (MCP) CRT. This oscilloscope offers extremely high speed writing, making one-shot pulses at nanosecond duration visible in normal room light. In that aspect it was the only non-storage CRT to be able to do this.
To the casual observer, a spectrum analyzer looks like an oscilloscope, ... the resolution bandwidth filter or RBW filter is the bandpass filter in the IF path.
In a typical 100 MHz bandwidth (e.g. an oscilloscope), a bandpass filter with width much narrower than 100 Hz would accomplish this. The averaging time of the lock-in amplifier determines the bandwidth and allows very narrow filters, less than 1 Hz if needed. However, this comes at the price of a slow response to changes in the signal.
Pico Technology offers passive and active oscilloscope probes up to 1.5 GHz, high-voltage and high-bandwidth differential voltage probes, current probes, thermocouples, accelerometers and pressure transducers. [10]
These oscilloscopes provided on screen controls setting. The 5000 series was the general purpose line while the 7000 series were capable of a wide variety of applications and could accept as many as 4 plug-ins. One model, the 7104 (introduced 1978), was a true 1 GHz bandwidth oscilloscope. [23]
